Upgrading a comp for a friend. He's thinking of getting an Epox EP-8KHA+ with an Athlon 1800+ XP Retail and 512mb Crucial PC2100 CL2.5. Is the motherboard top of the line? He doesn't want to spend money for Abit, is this the next best? Does that 1800+ provide the best price/performance? Or should he go a step lower? Also, is the retail heatsink adequate. Finally, will that RAM run CAS2? or should he try something different?
